for feedback on something like value scales pictures have to be taken with better lighting.. the upper left side of your pages is lit up while the bottom right is in shadow affecting all of your work on the page

Though I'm not able to view the video examples, to me, it looks super good! Don't see anything off about the perspective:)

Hello these look nice but, I think you focus a little too much on the contours. Remember, gesture is about the feeling. Make sure you time them as well I don't know if you did or not. You will never really just be good at these 2 minute poses until you've done them for months maybe even years so you will probably never really feel ready to move on to the next one. Stan himself in a podcast said you should spend a maximum of 2 weeks on each section of the course. I highly recommend listening to the draftsmen podcast while drawing. It's entertaining and informative. This is coming from someone who hates podcasts.

You can always try tagging an instructor when posting work. Just make sure not to do it too much
